Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Field Code Changed
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).

This fifth edition cancels and replaces the fourth edition (ISO 4063:2009), which has been technically
revised. 6778832cea66/iso-4063
The main change compared to the previous edition ischanges are as follows:
— — incorporation of processes and reference numbers for welding and thermal joining of plastics.

Welding, brazing, soldering and cutting — Nomenclature of
processes and reference numbers
1 Scope
This document establishes a nomenclature for:
— ― welding;
— ― brazing, soldering and weld brazing;
— ― thermal cutting;
with each process identified by a reference number.
It covers the main processes (one digit), groups (two digits) and sub-groups (three digits). The reference
number for any process has a maximum of three digits. This system is intended as an aid in
computerization, and the drafting of, for example, drawings, working papers and welding procedure
specifications, etc and enables the uniform international designation of the processes.
This document does not cover all process variants. The process numbers can be supplemented with
additional information for variants not listed.

4 Designation
4.1 General
Where a full designation is required for a joining process, it shall have the following structure: the number
of this document (i.e. “ISO 4063”), separated by a hyphendash from the reference number of the process,
as shown in these examples.
EXAMPLE 1 Process “Cold pressure welding” with reference number 48 is designated as:
ISO 4063 – 48
EXAMPLE 2 Process “Radio frequency welding” with reference number 62 is designated as:
ISO 4063 – 62
EXAMPLE 3 Process “Heated wedge welding with hot gas” with reference number 662-A is designated as:
ISO 4063 – 662-A
4.2 Hybrid joining processes
When multiple processes are used simultaneously in one process area, the processes shall be described
using the designations for each process separated by the symbol “+”.

ISO/FDIS 4063:2022(E)
EXAMPLE Process “Gas laser welding” (reference number 522) together with process “Plasma arc
welding” (reference number 15) is designated as:
ISO 4063 – 522+ + 15
5 List of processes and reference numbers
5.1 General
The first designation listed is the preferred one and any subsequent designationdesignations are
synonyms. Terms used in the United States of America (USA) are shown for information where there are
differences.
